Description
The Trane SWT1652 200 230°F auto limit switch is a critical safety temperature control used in furnaces, air handlers, and HVAC heating equipment to monitor internal heat levels. When internal air temperature reaches approximately 230°F, the switch opens to interrupt the electrical circuit and protect your system from overheating. Once temperatures drop back to a safe level (around 200°F), it automatically resets to resume normal operation.
Key Features
- Designed for 200°F close / 230°F open temperature range to protect against excessive internal heat.
- Automatic thermal limit switch that resets itself as temperatures normalize.
- 3″ insert length for proper engagement within furnace heat zones.
- Compact, durable construction for reliable performance.
- Simple installation with quick connect terminals (where applicable).
